I'm clear about salvage (7)
I believe the answer is:
reclaim
'salvage' is the definition.
(I've seen this before)
'i'm clear about' is the wordplay.
'about' indicates an anagram.
'im'+'clear'='imclear'
'imclear' with letters rearranged gives 'RECLAIM'.
(Other definitions for reclaim that I've seen before include "Retrieve, recover" , "'Make useful again, land say (7)'" , "recovery like this" , "Bring under cultivation" , "Get back (eg from the sea)" .)
